Answer:

d. Keisha did not make a mistake

Step-by-step explanation:

3+(-4)-7

3+(-4)+(-7) adding negatives is the same as subtracting

3+(-11) -4 and -7 do make -11

-8 3 and -11 do make -8

So she did it correctly, which means d is the right answer.

Answer:

437.3ft

Step-by-step explanation:

last of sines

a/sin(A) = b/sin(B) = c/sin(C)

sin(90) = 1

the angle between y and 500ft side is 90-29 = 61 degrees.

so,

x/sin(61) = 500/1 = 500

x = 500 × sin(61) = 437.3ft

In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

"Trigonometric ratio is defined as in a right triangle the relation between the ratio of a sides of a triangle and the angle."

Formula used

[tex]sin\theta = \frac{opposite sides}{hypotenuse}[/tex]

[tex]cos\theta = \frac{adjacent sides}{hypotenuse}[/tex]

According to the question,

In a given right triangle ABC,

Hypotenuse [tex]=500 ft[/tex]

Opposite side [tex]= x ft[/tex]

Adjacent side [tex]= y ft[/tex]

As per the diagram drawn,

 [tex]\angle BAC+ 29\° = 90\° \\\\\implies \angle BAC = 90\° -29\° \\\\\implies \angle BAC = 61\°[/tex]

Substitute the value in the above trigonometric ratio formula we get,

[tex]sin61\° = \frac{x}{500}\\\\\implies 0.8747 = \frac{x}{500}\\\\\implies x = 500 \ times 0.8747\\\\\implies x = 437.35 ft[/tex]

[tex]\implies x = 435.4 ft[/tex] (round to nearest tenth)

In trigonometric ratio [tex]cos\theta[/tex] we get,

[tex]cos61\° = \frac{y}{500}\\\\\implies 0.4848 = \frac{y}{500}\\\\\implies y= 500 \ times 0.4848\\\\\implies y = 242.2 ft[/tex]

Hence , In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

Step-by-step explanation:

A = P (1 + rt)

a= 8600(1+0.06*3)

a = 10148

Answer:

Option D

Step-by-step explanation:

Given the function [tex]g(x)=\frac{-7(x-5)^2(x+6)}{(x-5)(x+5)}[/tex], we see that [tex](x-5)[/tex] appears in both the numerator and denominator which cancel out to be [tex]\frac{-7(x-5)(x+6)}{(x+5)}[/tex]. This means that there's a vertical asymptote at [tex]x=-5[/tex] for the denominator to be 0.

Additionally, the limit of the function g(x) as x approaches -5 from the left side is -∞. The limit of the function g(x) as x approaches -5 from the right side is ∞. See the attached graph for a visual of these limits.

In conclusion, option D is correct.

Answer:

84

Step-by-step explanation:

m∠CMT=101-54=47

m∠PMA=37, So

m∠PMA+m∠CMT=47+37=84

The sum of the angle ∠PMA + ∠CMT will be 84 so option (D) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

In other words, the angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The Angle of description has given below

∠CMT=101-54=47

∠PMA=37, means

∠PMA+∠CMT = 47+37 = 84 hence, 84 will be the correct answer.

Answer:

The third option is the correct option

Answer:

21%

Step-by-step explanation:

Since both 100 and 79 is the percentage, you need to find how much has decreased, so you have to subtract.

100-79 = 21

So, 21% was decreased.

Answer:

Mean=85.5

Median=82

Mode=82

Range=25

Please would you mind marking me as the brainliest:)

Answer:

Mean: 85

Median: 82

Mode: 82

Range: 25

Step-by-step explanation:

The mean is the average of all of the numbers. You add all of the numbers together and then divide by the total amount of number you have. In this case you have 8 scores. So you add all the scores together, and then divide by 8:

82 + 78 + 82 + 80 + 100 + 96 + 75 + 91 = 684

684/8 = 85.5

So 85 is the mean.

The median is the number that is in the middle of all of the numbers listed. To do this, first list the numbers in order:

75, 78, 80, 82, 82, 91, 96, 100

The two numbers in the middle are both 82. So, 82 is the median.

The mode is the number that appears the most. In this problem, you can see that the number 82 appears twice. So 82 is the mode.

The range is the highest number minus the smallest number. Here, the highest number is 100. The smallest number is 75. So,

100 - 75 = 25

25 is the range.

Answer:

2.5

Step-by-step explanation:

a = 1

b = 5

ab

= 1 x 5

0.5b

= 0.5 x 5

= 2.5

ab - 0.5b

= 5 - 2.5

= 2.5

Answer:

2.5

Step-by-step explanation:

ab - 0.5b

a = 1 and b = 5

(1)(5) - 0.5(5)

Multiply (1)(5) = 5

5 - 0.5(5)

Multiply -0.5(5) = -2.5

5 - 2.5

Subtract 5 - 2.5 = 2.5

Answer:

See below.

Step-by-step explanation:

Graphing the points on the number line will spell the word 'LATE'.

However, when graphing the absolute values of the numbers, they will spell the word 'TEAL'.

This is due to using absolute value which makes any value positive.

Ex: |-8| = 8

     |-5| = 5

This value is approximate because pi = 22/7 is approximate.

===========================================================

Explanation:

Let's find the perimeter of the wheel, aka the circumference

C = pi*d

C = (22/7)*77

C = 242

The distance around the tire is approximately 242 cm

At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.

We can say the following

1 meter = 100 cm

242 meters = 24200 cm .... multiply both sides by 242

One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.

1 revolution = 242 cm

100 revolutions = 24200 cm ... multiply both sides by 100

---------------------------

We could also use a proportion to solve

(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)

1/242 = x/24200

1*24200 = 242x

242x = 24200

x = 24200/242

x = 100

Answer:

[tex]\displaystyle \sin E=\frac{20}{101}[/tex]

Step-by-step explanation:

Recall that sine is the ratio between the opposite side and the hypotenuse in a right triangle:

[tex]\displaystyle \sin x=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]

In the given triangle, with respect to E, the adjacent side is 99, and the hypotenuse is 101. So, we are not given the value of the opposite side.

Since it is a right triangle, we can use the Pythagorean Theorem. Hence:

[tex]OU^2+99^2=101^2[/tex]

Solving for OU (the opposite side) yields:

[tex]OU=\sqrt{101^2-99^2}=20[/tex]

Therefore, the opposite side is 20.

Hence:

[tex]\displaystyle \sin E=\frac{20}{101}[/tex]

Answer:

Step-by-step explanation:

There are three surfaces to add up to.

A1, the top surface of the cone (r=1,h=2)

A2, The curved surface of the cylinder (r=1 , h = 13-2 = 11)

A3, The circular base of the cylinder (r=1)

The slant height of the cone, s = sqrt(1^2+2^2), s = sqrt(5)

The length (circumference of the base), l = 2 pi r = 2pi r = 2pi

The area is

A1 pi s l = pi * sqrt(5) (2 pi r) = 2(pi^2)sqrt(5)

The curved surface has an area of

A2 = 2 pi r h = 2pi (1)(11) =22pi

The base has an area of

A3 = pi r^2 = pi

Total area = A1+A2+A3 = 2sqrt(5) (pi^2) + 22pi + pi

= 2sqrt(5) pi^2 + 23pi
